Just got my KS copy, read it through and very excited to run this. Is there a place (discord, etc) to discuss interpretation of the mechanics with you or other GMs? First question is about the d66 roll for COREs under salvage: many pages (17–20, 27-30, 37–40, etc) can never be rolled on d66...is that intentional? Such that the only way to find those COREs is on a salvage roll of 14?
This is the place, I suppose! You are correct, a lot of the more experimental/oddball COREs were put on the pages that can only be reached by "GM's choice".
I would encourage GM's to liberally hand out any that sound like fun, or if you'd like to disclaim the decision making, have the player roll a D100, and subtract 70 if the player rolls higher than that.
I wish you a good game!
